    Help with decision: what focal length macro?

    Hello!
    New to this forum and new to macro photography. Trying to produce some better shots of my watches and I am having a rough time with my stock lenses. My equiptment limitations have lead me on a quest for a macro lens . Can't decide which lens would be the best or most versital. A 30 mm macro, a 50 mm macro or 100 mm macro?

    What camera are you using and what lenses do you have in mind?

    From where I stand the 100mm focal length is a pretty safe choice on most dslr cameras, you can use it even for portraiture or insects (unless you want to shoot some really shy ones, in that case you can go all the way towards the 150-180-200mm range)

    +1 for what Haf posted, 90 - 105mm is a great choice as it gives you sufficent distance if you want to photograph insects and doubles as a good portrait / short zoom lens. 30 - 50mm would be great as walkabout lenses BUT you would have a very short minimal focal distance which would make insect shots nigh on impossible.

    Re: Help with decision: what focal length macro?

    Thanks for the responses! I am shooting with a Sony set up (brought over from my Minolta days). Have a very good range of lenses now but no macro lens. I have a 50mm that I use for portriats along with a 24mm-70mm 2.8. Which is awesome but not so good with Macro. Sony has a 30mm, 50mm and 100mm in there macro line that I am deciding on. I am leaning toward the 30mm because of the price and that I would be primarily going to use it to shoot watches and walk around lenses for flowers and things like that. Still like to still hear your opinions.

    The 30mm will be great for a walkaround / static shots, the problem with short macro lenses is you need to get VERY close to your subject so things like insect shots will be virtually impossible as you'll spook your quarry. One other (cheap) option is a macro adaptor like the Raynox DCR250 which I use for all my macro shots, it is quickly attached / detached from your lens and is dirt cheap. Using the Raynox with my kit 50-200mm lens you can easily get shots like this:

    I'm not sure why Sony makes a 30mm macro lens. It's such a short focal length - doesn't seem to make a lot of sense. But if the price of the SAL-30M28 is what you're attracted to ($199 at B&H Photo), try a set of Kenko extension tubes instead ($179 at B&H Photo). Here's a link to them:

    http://www.bhphotovideo.com/c/product/406965-REG/Kenko_AEXTUBEDGM_Auto_Extension_Tube_Set.html#feat ures

    Here's a snippet of information on them from the B&H Photo website:


    The Kenko Auto Extension Tube Set DG contains three tubes of different length - 12mm, 20mm, and 36mm - which can be used individually or in any combination to obtain the desired magnification. Actual magnification effect changes with each specific lens. Extension tubes are designed to enable a lens to focus closer than its normal set minimum focusing distance. Getting closer has the effect of magnifying your subject (making it appear larger in the viewfinder and in your pictures). They are exceptionally useful for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality.
    The extension tubes have no optics. They are mounted in between the camera body and lens to create more distance between the lens and film plane. By moving the lens father away from the film or CCD sensor in the camera, the lens is forced to focus much closer than normal. The greater the length of the extension tube, the closer the lens can focus.
    If you have to have a dedicated macro lens after you try this, save up and buy the SAL-100M28 lens.

    Re: Help with decision: what focal length macro?

    Fantastic! Thanks for the information and good suggestion on the Auto Extention tubes. It seems as if you need to have the camera on a tripod for best results which is OK. For hand held shots of flowers, insects, etc this may be a bit hard since the auto focusing is hard per the reviews.

    this may have made the finals of the decesion. The 100mm lens would be ideal but maybe a bit expensive at the moment.

    Thanks again,

    Michael

    It's pretty common for shorter prime lenses to have a pretty good magnification ratio at short focal distances. I've got a 28mm prime that can double as a (not 1:1 admittedly) macro that's good enough for general close-ups whilst out and about. Since it's not that high a magnification you stand a better chance of getting handheld shots, coupled with the shorter focal length if you use the rule of thumb "1 / focal length = minimum shutter speed that you can safely take handheld shots", so for my 28mm = 1/28th sec which is pretty slow.

    Re: Help with decision: what focal length macro?

    Hi -

    For macro work, a tripod - usually with a specialized macro head that allows for fine-tuning camera placement without moving the tripod for every small change - is invariably an absolute necessity.

    One aspect to consider is also depth of field: the shorter focal lengths will have greater depth of field at the same reproduction ratio by virtue of their focal length. While this can be an advantage for watches, the need of getting in very, very close is a disadvantage, usually, in the real world.
